Complex, Multicellular Life from Over Two Billion Years Ago Discovered
Sciencedaily.com ^ | 07/01/10

Posted on 07/06/2010 2:59:07 AM PDT by jerry557

The discovery in Gabon of more than 250 fossils in an excellent state of conservation has provided proof, for the first time, of the existence of multicellular organisms 2.1 billion years ago. This finding represents a major breakthrough: until now, the first complex life forms (made up of several cells) dated from around 600 million years ago.

---snip---

By studying the sedimentary structures of this site, the scientists have shown that these organisms lived in a shallow marine environment (20 to 30 meters), often calm but periodically subjected to the combined influence of tides, waves and storms. In order to be able to develop 2.1 billion years ago and become differentiated to a degree never attained previously, the authors suggest that these life forms probably benefited from the significant but temporary increase in oxygen concentration in the atmosphere, which occurred between 2.45 and 2 billion years ago. Then, 1.9 billion years ago, the level of oxygen in the atmosphere fell suddenly.

Until now, it has been assumed that organized multicellular life appeared around 0.6 billion years ago and that before then the Earth was mainly populated by microbes (viruses, bacteria, parasites, etc.). This new discovery moves the cursor of the origin of multicellular life back by 1.5 billion years and reveals that cells had begun to cooperate with each other to form more complex and larger structures than single-celled organisms. Several research avenues now need to be explored: understanding the history of the Gabonese basin and why the necessary conditions were gathered to enable this organized and complex life to exist; further exploring the site to enhance the collection of fossils; but also comparing the history of the Earth's oxygenation with the mineralization of clays. The most urgent task, however, remains the protection of this exceptional site.

Would you also conclude that griffins existed in medeval Europe?

medieval -

what you choose to ignore it that the creatures depicted by pre-historic artists have been shown to have existed by the discovery of FOSSILS.

Fossils have been found exposed by natural erosion. We look at fossils and draw depctions of what we think they might have looked like based on those fossils. Do you disallow the possibility that those depictions may be the result of preistoric people having stumbled onto fossil remains of the same animals we've discovered?

Hey, Fred. Follow this and it all becomes clear.

I’ve been studying Afrophysics. I’ve discovered Obama isn’t really black. He’s just so dense, light bends around him. However, this density causes acretin disc to form around him, making him appear brighter than he really is. As you know, the closer you are to His kind of Singularity, the more time slows. So your position relative to the O can cause some wild variations in time.

This being the case, why not? (what you said)

And thus, the griffin? Interesting idea. Fossil of a winged mammal?

I KNEW you would. So here's the thing, Fred. I believe the power of the human mind is bounded only by the matrix wherein it is confined.

For most peeple...testing...testing...is this thing on?...

Oh No!! His Presidency has already seemed like an Eternity!

What would have prevented Indians from seeing dino fossils and incorporated those images into their paintings?

The main problem, as I see it, is the O has no concept of my every today existence. What for me is today, won’t cross his awareness for several months. So when he says “It isn’t as bad as it could be”, that has no relevance in my current time. It is as bad as it could be. By the “time” he catches up with “today”, his term as POTUS will be so over. Not that that will do this BDMF any good.

Having better things to do. Generally at least. Lewis and Clarke reported their Indian guides being in mortal terror of the Mishipishu/stegosaur glyphs around the Mississippi and the meaning of the things was clear enough i.e. they were warnings, saying "Be careful, one of these things lives close by". I mean, the things weren't just art work for art's sake.

Amerind artists would touch them up every few decades or so which is why they still exist and the stegosaur was long gone by the time a later artist added the horns which you see on the image from Agawa Rock at Massinaw, Lake Superior.

That’s an interesting theory. I see him as an acretin disk surrounding an enormous black a-hole. It has a very large Schwarzenegger radius and is of sufficient size to absorb all current and future tax money. I’m afraid the events on his horizon will eventually result in a big bang.

As I was observing the fossil remains of a stegosaurus similar to the one shown posted above, a man came up shaking his head and wondering out loud, "can you imagine hunting one of those with only a spear."

I did not reply

In the painted desert park there is a petroglyph depicting the weblos badge

The horns in the petroglyph at massinaw were added at a much more recent time. Amerind oral traditions describe the water panther as having red fur, a sawblade back, and a “great spiked tail” as the glyphs show. No modern animal has a sawblade back or a spiked tail.

“The basic hard, cold reality is that evolution and evoloserism and all of the fairytale time schemes devised to support evolution are dead. “

Prefacing nonsense with a curseword always helps a vacuous argument.

So, your argument is that pictures on a wall from an illiterate savage trump the science of millenia and the intellectual giants that have pursued it over those thousands of years.

Your argument parodies itself.
